The term `accountability' is described in various ways depending on the domain in which it is used. In public administration, is means how an individual or entity can be accountable to the public. Similarly, electronic health records are meant to manage and control how patients provide access to their own records (give authorization to doctors or others who may need to see his/her patient records). In electronic commerce, accountability involves access or denial to parties for transactions. Various researchers have proposed protocols to analyze accountability for internet transactions, particularly payment transactions. However, such protocols continue to lack sufficient security properties. A secure payment protocol was proposed which included security properties and accountability. The protocol may provide enhanced effectiveness for accountability in payment transactions as well as other forms of internet-based transactions. The protocol was designed utilizing a public key cryptography and a hash function in order to guarantee that our proposed protocol is compliance with all necessary security properties.
